British reality TV star Len Goodman will ring in 2013 with a new wife after marrying in secret on Sunday. The professional ballroom dancer, who serves as a judge on "Dancing With the Stars," exchanged vows with dance teacher Sue Barrett, his partner of more than 10 years. The couple invited 30 relatives and close friends to lunch at Mosimann's private restaurant in London, and took their guests by surprise when they stood up for the ceremony.

Goodman tells Britain's Daily Mail, "I've had a marvelous day, and now my gorgeous Sue is the new Mrs. Goodman."

"I wanted it to be a low-key affair, so we didn't tell anyone except my 96-year-old mum, as I didn't want her having a heart attack with the surprise. We've had a marvelous day, with marvelous food, surrounded by all my dearest friends -- and it didn't go on for too long, so it didn't get boring!

"I've been going out with my lovely Sue for ages, and I decided it was time to pop the question. She's gorgeous and makes me very happy -- though she likes to stay out of the limelight. It was a complete surprise to my friends and family today, and we've had a fabulous time."

Goodman was previously married to his dance partner Cherry Kingston and has a 31-year-old son, James, with his second wife, Lesley.
